Terahertz Pulses Create chirality in Non-Chiral Crystals Understanding Chirality in Crystals Chirality describes objects that cannot be perfectly aligned with their images, regardless of rotations or translations — similar to how left and right human hands differ. In chiral crystals, the atomic arrangement imparts a unique "handedness," affecting properties such as optical behavior and electrical conductivity. Research Focus: Antiferro-Chiral Crystals Characteristics of Antiferro-Chiral Crystals A research collaboration between Hamburg and Oxford has studied antiferro-chiral crystals, a type of non-chiral structure analogous to antiferromagnetic materials, where magnetic moments anti-align in a staggered pattern, resulting in no net magnetization. Composition of Antiferro-Chiral Crystals These crystals contain equal proportions of left-and right-handed substructures within a unit cell, making them overall non-chiral.
